| Abstract:In this study， relatively high-substitution-degree cationic guar gum was successfully prepared by chemically modifying guar gum using betaine acyl chloride as a cationic reagent under pyridine catalysis. The results showed that under optimized reaction conditions (guar gum to betaine acyl chloride mass ratio of 4∶2， pyridine dosage of 8.5%， reaction temperature of 80 ℃， and time of 2 h)， the degree of substitution of the cationic guar gum reached 0.098， while the initial viscosity of guar gum was well retained. Thermogravimetric analysis demonstrated a significant improvement in the thermal stability of the modified cationic guar gum. Scanning electron microscopy revealed a porous structure on its surface， confirming that the reaction occurred uniformly both on the surface and within the guar gum matrix. When applied to cigarette paper production， the filler retention efficiency increased with the dosage of cationic guar gum. At a dosage of 0.15% (relative to the total mass of cigarette paper)， the filler retention rate peaked at 56.7%， and the chromium content in the cigarette paper was 1.63 mg/kg， complying with GB 29949—2013. |
